gramps 305706956e TASK 51 jitter fix: temporal mask smoothing. MaskSmoother blends each raw segmentation 0.75xnew + 0.25xprevious at the one CameraManager worker (state per CameraSession, not in the shared segmenter); null resets history, first frame passes through, input array never aliased, ping-pong buffers (no LOH alloc for a 147KB 256x144 mask). Creator's real-camera check: Remove was 'jittery' (per-frame independent segmentation). Weights from the OBS/Jitsi consensus. One integration test asserts the second frame keeps partial alpha (x=6 -> 58) where the raw mask cuts to 0. 416 pass / 2 known env flakes.
